Man United paid Porto £20m for Anderson in 2007, but in the eight years at Old Trafford he was unable to fulfil the massive potential he clearly had. He was the best player at the 2005 U17 World Cup then won the Golden Boy award in 2008. Injuries didn’t help and he didn’t always appear to be in top physical shape, yet he won the Champions League and four Premier League titles. A number of scouts had been monitoring him for a while prior to his signing and Sir Alex Ferguson revealed in his autobiography that his brother, Martin, told him Anderson was better than Wayne Rooney. He wasn't and was eventually moved on to Internacional in 2015.

Nominees for the annual Golden Boy award has been announced and it features six Premier League-based players.

The prize is given to the best player in Europe under the age of 21 and has been handed out by Italian news outlet Tuttosport since 2003. Judges are formed of various journalists around the Continent and included The Times in England.
